Apple recently removed Fortnite from its App Store and only hours later Google also removed the Fortnite app from its Google Play Store. It all started when changes were made in the Fortnite app for the App Store and later in Google's version of the app. As a result of the changes, players were able to by-pass Google's in-app purchase system, which was against Google's guidelines.
According to the guidelines of Google, products that are offered in a game download on Google Play must use the Google Play In-App Billing method for payment, and the same rule applies for access to game content. Google's in-app purchase policy is designed to keep the Play Store safe for users, according to the company.
Google's statement to The Verge said that even though Fortnite is available on Android, it can't be made available on Google Play as it violates Google's policies. The company has, nevertheless, expressed that it is open to discussions with Epic, developer of Fortnite, and can bring the game app back to Google Play with mutual agreements. Google also clarified that it has no issue with Fortnite being distributed on Android devices, but for it to be available on the Play Store, Epic must follow Google's guidelines.
Fortnite is no more available on the Google Play Store, but can be used on Android and be downloaded via the Epic Games app or Samsung's Galaxy Store.
